Step by step solution

01

Step: 1 Finding the value for diagram:

Position of two charges at potential is

U(x)=2q4蟺系0|x|+(鈭�q)4蟺系0|x鈭�3|

Where localid="1648820269317" x=0in localid="1648820266806" 2qcharge and localid="1648820252518" x=3in localid="1648820260629" -qcharge.

Step: 2 Finding value and reproducing diagram:

Substituting Ux=0and the value of xis obtained and the diagram is

The electron gun in an old TV picture tube accelerates electrons between two parallel plates 1.2 cm apart with a 25 kV potential difference between them. The electrons enter through a small hole in the negative plate, accelerate, then exit through a small hole in the positive plate. Assume that the holes are small enough not to affect the electric field or potential.

a. What is the electric field strength between the plates?

b. With what speed does an electron exit the electron gun if its entry speed is close to zero?

Note: The exit speed is so fast that we really need to use the theory of relativity to compute an accurate value.

Your answer to part b is in the right range but a little too big.

A student wants to make a very small particle accelerator using a 9.0 V battery. What speed will (a) a proton and (b) an electron have after being accelerated from rest through the 9.0 V potential difference?

A 1.0-mm-diameter ball bearing has 2.0脳109excess electrons.

What is the ball bearing鈥檚 potential?

What is the potential energy of the electron-proton interactions in FIGURE EX25.5? The electrons are fixed and cannot move.
